On behalf of the dune team, I'm pleased to announce version 3.1.0. This release contains some small, but interesting features, and some important quality of life bug fixes. I encourage everyone to upgrade as soon as possible.
Happy Hacking.
Add sourcehut
as an option for defining project sources in dune-project
files. For example, (source (sourcehut user/repo))
. (#5564, @rgrinberg)
Add dune coq top
command for running a Coq toplevel (#5457, @rlepigre)
Fix dune exec dumping database in wrong directory (#5544, @bobot)
Always output absolute paths for locations in RPC reported diagnostics (#5539, @rgrinberg)
Add (deps <deps>)
in ctype field (#5346, @bobot)
Add (include <file>)
constructor to dependency specifications. This can be
used to introduce dynamic dependencies (#5442, @anmonteiro)
Ensure that dune describe
computes a transitively closed set of
libraries (#5395, @esope)
Add direct dependencies to $ dune describe output (#5412, @esope)
Show auto-detected concurrency on Windows too (#5502, @MisterDA)
Fix operations that remove folders with absolute path. This happens when using esy (#5507, @EduardoRFS)
Dune will not fail if some directories are non-empty when uninstalling. (#5543, fixes #5542, @nojb)
coqdep
now depends only on the filesystem layout of the .v files,
and not on their contents (#5547, helps with #5100, @ejgallego)
The mdx stanza 0.2 can now be used with (implicit_transitive_deps false)
(#5558, fixes #5499, @emillon)
Fix missing parenthesis in printing of corresponding terminal command for
(with-outputs-to )
(#5551, fixes #5546, @Alizter)
On behalf of the ocamllsp team, I’m excited to announce the availability of version 1.11.0. This release is an important milestone for the project because it introduces integration with our favorite build system. When you run dune in watch mode, you will now be able to see build errors in the diagnostics panel of your editor. It’s all rather experimental for now, so your feedback and bug reports are appreciated.
As usual, the full change log is below.
Happy hacking.
Add support for dune in watch mode. The lsp server will now display build errors in the diagnostics and offer promotion code actions.

On behalf of the ocamllsp team, I’m pleased to announce version 1.10.0. The only new feature this release offers is better code folding, but there are some important bug fixes and performance improvements. If you encounter any sluggishness with our server, do not hesitate to report it.
Unless there are serious bugs with this release, this will be the last release for OCaml 4.13.
Happy Hacking.
Fix infer interface code action crash when implementation source does not exist (#597)
Improve error message when the reason plugin for merlin is absent (#608)
Fix chdir

More accurate completion kinds. New completion kinds for variants and fields. Removed inaccurate completion kinds for constructors and types. (#510)
Fix handling request cancellation (#616)
On behalf of the dune team, I’m delighted to announce the availability of dune 3.0.
The team has been working on this release for over 6 months, and there’s a bunch of new work to report. I’ll only highlight the some of the interesting new developments:
The watch mode has been rewritten from scratch to be faster and more scalable. We also no longer rely on any 3rd party tools such as fswatch. If any of you still have a dune workspace dune is still struggling with, we cannot wait to hear from you.
The watch mode now also starts an RPC server in the background. This RPC protocol is going to be the basis for other tools to interact with dune. Watch out for announcement on the LSP side to see how we’ll be making use of it to improve the editing experience.
The dune cache has been rewritten as well. It is now simpler and more reliable. There are still some components missing, such as distribution of the artifacts over the network. Nevertheless, we welcome you all to experiment with this feature and give us feedback.
We’ve addressed one of our oldest feature requests: high level rules for ctypes projects. This feature is still experimental, so we need feedback from real world projects before declaring it as mature.
Of course, there are many other fixes, enhancements, and only a few breaking changes in this release. We hope you have an easy time upgrading.
Happy Hacking.

the dune-project file. (#4867, fix #2882, @kit-ty-kate, @rgrinberg)
Add link_flags
field to the executable
field of inline_tests

exclusively (#4941, @rgrinberg)
Report cycles between virtual libraries and their implementation (#5050, fixes #2896, @rgrinberg)
Warn when lang versions have an ignored suffix. (lang dune 2.3.4)

inside a tests
stanza. Previously, dune would crash
when this field was present (#4942, fix #4946, @rgrinberg)

field to inline_tests
within the library
stanza.
This allows us to disable executing the inline tests while still allowing for
compilation (#4939, @rgrinberg)
Generate a dune-project
when initializing projects with dune init proj ...
(#4881, closes #4367, @shonfeder)

(#4170, @bobot)
Allow %{version:pkg}
to work for external packages (#4104, @kit-ty-kate)
Add (glob_files_rec <dir>/<glob>)
for globbing files recursively (#4176,
@jeremiedimino)
Automatically generate empty .mli
files for executables and tests (#3768,
fixes #3745, @CraigFe)
Add ocaml
command subgroup for OCaml related commands such as utop
, top
,
and merlin
(#3936, @rgrinberg).
Detect unknown variables more eagerly (#4184, @jeremiedimino)
Improve location of variables and macros in error messages (#4205, @jeremiedimino)
Auto-detect dune-project
files as dune
files in Emacs (#4222, @shonfeder)
Dune no longer automatically create or edit dune-project
files
(#4239, fixes #4108, @jeremiedimino)
Warn if dune-project
is not found (fatal in release mode) (#5343, @emillon)
Cleanup temporary files after running $ dune exec
. (#4260, fixes #4243,
@rgrinberg)
Add a new subcommand dune ocaml dump-dot-merlin
that prints a mix of all the
merlin configuration of a directory (defaulting to the current directory) in
the Merlin configuration syntax. (#4250, @voodoos)
Enable cram tests by default (#4262, @rgrinberg)
Drop support for opam 1.x (#4280, @jeremiedimino)
Stop calling ocamlfind
to determine the library search path or
library installation directory. This makes the behavior of Dune
simpler and more reproducible (#4281, @jeremiedimino)
Remove the external-lib-deps
command. This command was only
approximative and the cost of maintainance was getting too high. We
removed it to make room for new more important features (#4298,
@jeremiedimino)
It is now possible to define action dependencies through a chain of aliases. (#4303, @aalekseyev)
If an .ml file is not used by an executable, Dune no longer report parsing error in this file (#4330, @jeremiedimino)
Add support for sandboxing using hard links (#4360, Andrey Mokhov)
Fix dune crash when subdir
is an absolute path (#4366, @anmonteiro)
Changed the implementation of actions attached to aliases, as in
(rule (alias runtest) (action (run ./test)))
. A visible result for
users is that such actions are now memoized for longer. For
instance:
$ echo '(rule (alias runtest) (action (echo "X=%{env:X=0}\n")))` > dune
$ X=1 dune runtest
X=1
$ X=2 dune runtest
X=2
$ X=1 dune runtest
Previously, Dune would have re-executed the action again at the last line. Now it remembers the result of the first execution.
Fix a bug where dune would always re-run all actions that produce symlinks, even if their dependencies did not change. (#4405, @aalekseyev)
Fix a bug that was causing Dune to re-hash generated files more often than necessary (#4419, @jeremiedimino)
Fields allowed in the config file are now also allowed in the workspace file (#4426, @jeremiedimino)
Add options to control how Dune should handle stdout and stderr of actions when then succeed. It is now possible to ask Dune to ignore the stdout of actions when they succeed or to request that the stderr of actions must be empty. This allows to reduce the noise of large builds (#4422, #4515, @jeremiedimino)
The @all
alias no longer depends directly on copies of files from the source
directory (#4461, @nojb)
Allow dune-file as an alternative file name for dune files (needs to be enabled in the dune-project file) (#4428, @nojb)
Drop support for upgrading jbuilder projects (#4473, @jeremiedimino)
Extend the environment variable BUILD_PATH_PREFIX_MAP
to rewrite
the root of the build dir (or sandbox) to /workspace_root
(#4466,
@jeremiedimino)
Simplify the implementation of build cache. We stop using the cache daemon to access the cache and instead write to and read from it directly. The new cache implementation is based on Jenga's cache library, which was thoroughly tested on large-scale builds. Using Jenga's cache library will also make it easier for us to port Jenga's cloud cache to Dune. (#4443, #4465, Andrey Mokhov)
More informative error message when Dune can't read a target that's supposed to be produced by the action. Old message is still produced on ENOENT, but other errors deserve a more detailed report. (#4501, @aalekseyev)
Fixed a bug where a sandboxed action would fail if it declares no dependencies in
its initial working directory or any directory it chdir
s into. (#4509, @aalekseyev)
Fix a crash when clearing temporary directories (#4489, #4529, Andrey Mokhov)
Dune now memoizes all errors when running in the file-watching mode. This speeds up incremental rebuilds but may be inconvenient in rare cases, e.g. if a build action fails due to a spurious error, such as running out of memory. Right now, the only way to force such actions to be rebuilt is to restart Dune, which clears all memoized errors. In future, we would like to provide a way to rerun all actions failed due to errors without restarting the build, e.g. via a Dune RPC call. (#4522, Andrey Mokhov)
Remove dune compute
. It was broken and unused (#4540,
@jeremiedimino)
No longer generate an approximate merlin files when computing the ocaml flags fails, for instance because they include the contents of a file that failed to build. This was a niche feature and it was getting in the way of making Dune's core better. (#4607, @jeremiedimino)
Make Dune display the progress indicator in all output modes except quiet (#4618, @aalekseyev)
Report accurate process timing information in trace mode (enabled with
--trace-file
) (#4517, @rgrinberg)
Do not log live_words
and free_words
in trace file. This allows using
Gc.quick_stat
which does not scan the heap. (#4643, @emillon)
Don't let command run by Dune observe the environment variable
INSIDE_EMACS
in order to improve reproducibility (#4680,
@jeremiedimino)
Fix root_module
when used in public libraries (#4685, fixes #4684,
@rgrinberg, @CraigFe)
Fix root_module
when used with preprocessing (#4683, fixes #4682,
@rgrinberg, @CraigFe)
Display Coq profile flags in dune printenv
(#4767, @ejgallego)
Introduce mdx stanza 0.2, requiring mdx >= 1.9.0, with a new generic deps
field and the possibility to statically link libraries
in the test
executable. (#3956, #5391, fixes #3955)
Improve lookup of optional or disabled binaries. Previously, we'd treat every executable with missing libraries as optional. Now, we treat make sure to look at the library's optional or enabled_if status (#4786).
Always use 7 char hash prefix in build info version (#4857, @jberdine, fixes #4855)
Allow to explicitly disable/enable the use of dune subst
by adding a
new (subst <disable|enable>)
stanza to the dune-project
file.
(#4864, @kit-ty-kate)
Simplify the way dune
discovers the root of the workspace. It now
stops at the first dune-workspace
file it encounters, and fails if
it finds neither a dune-workspace
nor a dune-project
file
(#4921, fixes #4459, @jeremiedimino)
Dune no longer reads installed META files for libraries distributed with the compiler, instead using its own internal database. (#4946, @nojb)
Add support for (empty_module_interface_if_absent)
in executable and library
stanzas. (#4955, @nojb)
Add support for %{bin-available:...}
(#4995, @jeremiedimino)
Make sure running git
or hg
in a sandboxed action, such as a
cram test cannot escape the sandbox and pick up some random git or
mercurial repository on the file system (#4996, @jeremiedimino)
Allow %{read:...}
in more places such as (enabled_if ...)
(#4994, @jeremiedimino)
Run each action in its own process group so that we don't leave stray processes behind when killing actions (#4998, @jeremiedimino)
Add an option expand_aliases_in_sandbox
(#5003, @jeremiedimino)
Allow to cancel the initial scan via Control+C (#4460, fixes #4364 @jeremiedimino)
Add experimental support for directory targets (#3316, #5025, Andrey Mokhov),
enabled via (using directory-targets 0.1)
in dune-project
.
Delete old promote-into
, promote-until-clean
and promote-until-clean-into
syntax (#5091, Andrey Mokhov).
Add link_flags in the env stanza (#5215)

(#342, @Leonidas-from-XIV)We are pleased to announce the minor release of opam 2.1.2.
This opam release consists of backported fixes, including:
dnf
if yum
does not exist on RHEL-based systems (#4825)--no-depexts
in CLI 2.0 mode. This further improves the use of opam 2.1 as a drop-in replacement for opam 2.0 in CI, for example with setup-ocaml in GitHub Actions. (#4908)Opam installation instructions (unchanged):
From binaries: run
bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --version 2.1.2"
or download manually from the GitHub "Releases" page to your PATH. In this case, don't forget to run opam init --reinit -ni
to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script.
From source, using opam:
opam update; opam install opam-devel
(then copy the opam binary to your PATH as explained, and don't forget to run opam init --reinit -ni
to enable sandboxing if you had version 2.0.0~rc manually installed or to update your sandbox script)
From source, manually: see the instructions in the README.
We hope you enjoy this new minor version, and remain open to bug reports and suggestions.
